Brief Overview, Current Activities & ARRA Improvements

CISN is a collaborative effort to integrate separate earthquake monitoring networks in California into a single system. It coordinates earthquake monitoring operations and provides rapid information distribution for emergency response and research purposes. Funding and current activities include station upgrades, waveform exchange, metadata management, and network expansion.

  1. Brief Overview, Current Activities & ARRA Improvements David Oppenheimer – USGS Menlo Park

  2. What is the CISN? • The California Integrated Seismic Network is a collaborative effort, founded in 2000, to integrate existing, separate California earthquake monitoring networks into a single seismic monitoring system. • The CISN provides the organizational framework to coordinate these earthquake-monitoring operations. • The CISN constitutes the California region within Advanced National Seismic System (ANSS).

  3. Who is the CISN? • Core members have primary responsibility for the recording and monitoring of earthquakes and the creation of CISN products • California Geological Survey • U.C. Berkeley Seismological Laboratory • Caltech Seismological Laboratory • Menlo Park USGS • Pasadena USGS • USGS National Strong Motion Program

  4. Who is the CISN? Participating members contribute to CISN activities through data exchange. • UC Santa Barbara • UC San Diego • University of Nevada Reno • CA Department of Water Resources • Lawrence Livermore National Labs • Calpine • Cal Energy • Lawrence Berkeley National Labs • PG&E • Plate Boundary Observatory (previously)

  5. CISN Goals • Operate a reliable and robust statewide system to record earthquake ground motions over the relevant range of frequencies and shaking levels • Distribute information about earthquakes rapidly after their occurrence for emergency response and public information • Create an easily accessible archive of California earthquake data for engineering and seismological research, including waveform data and derived products

  6. 2005 Funding Total ~$16M

  8. Current Software Activities • ShakeMap Upgrade • Metadata management (SIS) • Station/Quake XML • Statewide ML analysis • National support of AQMS • Waveform exchange with CGS • RT Double Difference

  9. Station/telemetry Upgrades • ARRA • Caltech -178 stations • UCB – 47 stations • NCSN - 8 stations • Microwave expansion • VA • NSMP – 7 CA hospitals • DOI • NCSN - 5 microwave facilities hardened

  10. Installs/UpgradesCGS SMIP • 30 stations installed, 12 in Bay area, 18 in southern California • Downhole arrays each side of Hayward fault and at Oakland end of new Bay Bridge, with Caltrans • SF Rincon Tower underway, with USGS • 2 hospitals, Ontario and San Jose, with OSHPD • BART TransBay Tube underway • 25 accelerographs installed in Parkfield to replace film recorders

  11. NetQuakes • 125 instruments now installed in NC; 50 more in 2012 • 32 instruments installed in SC; 35 more in 2012 • Partnerships with EBMUD, San Diego Gas and Electric, and CICESE • Providing national support for additional 117 installed, 100 in process.
